In addition, the biomaterial can easily be fixed to surrounding tissues, and which is extended and reduced only in the same direction as that of an adaptable tissue and has an extending and reducing quantity equal to that of the adaptable tissue, thereby it is possible to prevent occurrence of the unnatural feeling, a pain and malfunction. Furthermore, until the tissue at a place where the biomaterial is adapted is reproduced completely, the biomaterial surely functions as a scaffold.  <P>COPYRIGHT: (C)2004,JPO
